This invention relatesto machines for use in the manufacture of boots and shoes and is illustrated as embodied ina machine for lastingstitchdown'shoes. p V V In the lasting of stitchdown shoes the outturne'd marginal portion or flange of a shoe upper is commonly securedto the marginal portion ofa sole member which extends beyond the 'lasthbottom 'either '"by staples or by cement; In the former case 'theupper is worked overthe last and the marginal portion of the shoe upper is brou ht 'into parallel relation with the sole memher thus forming a flange. Staples are driven through theupper into the sole member at the apex of the angle between the side of the last and the projectingma'rgin of the sole. This operation is commonly performed by stitchdown staple lasting machines 0f the type disclosed in. Letters Patentof the United States 'No .'1,29l,75 l, grant ed January 21,1919, on an application filed in the name'of Matthias' Brock. In the case of cement lasting-of stitchdown shoes, the cement isusuallyappliec'l'both to the:fiesh side ofthe marginal'portion of the upper and to the surface of the projecting mar-' ginal portion of the sole member. After the cement has become tacky the upper is worked over the last and the outwardly turned marginal portion of the upper is caused to adhere to the sole member by pressure, the lasting and pressing operations being carried out step-bystep or progressively, for example by a machine such as [thatdisclosed in Letters Patent of l the 7 United States, No. 1,720,212,granted July 9, 1929, on an application filed in the name portionof the same shoe, as well as to secure the upper in lasted relation to the soleby staples while operating uponone shoe, and

by cement when operating upon another."

With this object in View, we have modifie da stitchdown staple lasting machine of the type disclosed in said Letters Patent-of the'United States No. 1,291,754, so asto adapt 1t to use-for cement lasting without in anyway interfering with' its effectiveness" as astaple lasting machine. Inthis machine we have provided mechanism-for latching 1 the driverbar of -the machine in'inoperative position and for rendering thefeed'rolls in- "operative to feed -wirelto the severing and staple forming-mechanism, without, however, interfering in any way with thee eration of the other parts of the mac-inc. Thus the work supportmayfbe raised manually to cause the'nozzle of the machine to wipetheuipper over the side'- of the last and 'intothe anglebetween the side of the 1 .last and the projecting margin offthe sole to which latter the upper is tobe secured;

'then, by the application of powerfthe =outwardly extending m arginalportions ofthe upper and the sole member may be clamped or squeezed together thus causlngthe oement with which those portions have been formation or: driving of staples. l i i I The sole engaging surface of a work support of the type commonly used'in stitchdown "previously coated to adhere, all withoutfthe staple lasting machines is provided with a shoulderor ledge, as shown in Letters Patent of the United States No. 1,200,464, granted October 10, 1926, on anotherapplication filed in the name of Matthias Brock. This shoulder is arranged to engage the soleto prevent slipping thereof whenthe sole issqueezedbetween the nozzle of the machine andthe work sup port and isccommonly provided also with a clenching surface for the legs of the staples. To prevent the marring of the surface of the :sole remotefrom the:upper, which surfaces may be and in some instancesis the tread-surface of the finished sole, a feature of the invention compr ses the provision of a member having a smooth sole'engaglng surface adapted to be moved. into position over the shouldered sole engaging surface ofthework sup (port of astitchdownstaple lasting machine when the machine is used for cement lasting. WVith the above and other objects and features in View, theinvention'will now be described in connection with the accompanying drawings and pointed out in the claims.

The invention is illustrated herein as embodied in a stitchdown lasting machine of the type disclosed in said Letters Patent of the United States No. 1,291,754 to which reference may be had for a description of the 25 construction and operation of such of the parts of the machine as it has been unnecessary to describe and illustrate in this specification.

The illustrated machine is provided with a head 10 (Figs. 1 and 2) carried at the upper end of a column 12. A shaft 14 is j ournaled in the head 10 and is driven from a constantly rotatingpulley 16 through a suitable clutch arranged to be connected and disconnected to the shaft 14 through suitable controlling mechanism 18 connected by a treadle rod 20 with a treadle 22 fulcrumed at 23 to the base of the column 12. Depression of the treaclle .22 is thus effective to cause the rotation of the shaft 14.

A reel 26 carried by a bracket 28 supported upon the head 10 of the machine (shown in WVilliam H. Borden, the feed rolls 32, 34 and the knives 36 are carried by a bracket 40 mounted for horizontal adjustment transversely of the machine by horizontal swinging movement of a hand lever 42 to which the bracket 40 is connected. The feed roll 32 is oscillated through adjustable connections 44 from a lever 45 fulcrumed on the head 10 0f the machine and rocked by a cam 46 on the shaft 14, the arrangement being such that when the lever 42 is moved to vary the length of wire fed, the bracket 40, the feed rolls 32, 34 and the cutter 36 move to the left half as -much as any increase in the length of the wire crease in the length of the wire fed so that the change in the length of the wire will be distributed equally between the two legs of the staples formed from the wire. The details of this construction are fully set forth in said Letters Patent No. 1,016,930 to which reference may be had for a fuller disclosure of those parts of the machine.

The wire 30 is fed, in the manner just described, above an inside former 48 and below a pair of outside formers 50 by which the lengths of wire severed by the cutter 36 are formed into staples which are driven into a work piece presented to the nozzle 52 of the machine by a driver 54 carried at the lower end of a driver bar 56. The upper end of the driver bar 56 is connected by a link 58 with one end of a coil spring 60, the other end of which is anchored to a bracket 62carried by the head 10 of the machine. A lifting cam 64 carried by the shaft 14 is arranged as it rotates to engage a lifting block 66 carried by the driver bar 56 and to lift the driver bar against the compression of the spring so that when the raised portion of the cam 64 passes out from beneath the lifting block 66,

the driver bar 56 and the driver 54 will be forced downwardly by the spring 60 driving into the work piece a staple which at that time is positioned in the path of movement of the driver 54 and in alinement with the driver passage of the nozzle 52.

The work support of the illustrated ma chine comprises a post 70 mounted for vertical sliding movement in bearings 72 (Fig. 1) formed in a bracket 7 4 carried by the column 12 of the machine. Carried at the upper end of the post 70 is an anvil support 76 having an arcuate upper surface formed to receive an anvil block 7 8 formed with a transversely extending shoulder or ledge 80 (Fig. 3) formed and arranged to prevent slipping of a work piece clamped between the upwardly inclined surface of the anvil block and an inclined surface 82 (Fig. 1) formed at the lower end of the nozzle 52 and serving as an abutment to limit upward movement of the work piece.

The shoulder 80 or the portion of the surface of the anvil block 78 into which it merges may constitute or be provided with a clenching surface or surfaces arranged to insure and control the clenching of staples driven through a work piece supported on the anvil block 78.

In accordance with the invention of said Letters Patent of the United States No. 1,291,? 54, the illustrated machine is provided with manually controlled means for raising the anvil block 78 preliminarily to clamping a work piece between the anvil block 78 and the nozzle 52 of the machine and with power operated means to increase the clamping pressure and to drive a staple into the work piece to hold together the parts thereof. Thus a lever 90 fulcrumed at 92 to the lower its rearward end (to the left as viewed in Fig. 1) the lever 90 is connected (by a link 96with a treadle 98 also fulcrumed at 23 to thebase of thQ'COlLUhn 12,'the arrangement being such that depression of the treadle 98 is operative to raise the post and the anvil block- 78' without n any way affecting the power driven parts ofthe machine. A wedge 104, mounted for horizontal slidingmove- -ment in ways 106' carried by the bracket 74,

is pivoted at its rear'end tothe depending arm of a ,bellcrank lever 108. The other arm of the bellcrank; lever 108 extends rearwardly and is pivoted to thelower end of a rod 110 which extends upwardly through a hole in the horizontally extending arm of a bellcrank lever 112 'fulcrumed at 114 to the head ofthe machine and arranged to be rocked by a cam 116 when the shaft 14 is rotated; Bearing against the upper surface of the horizontally extending arm of the bell crank lever 112 is a nut 120 threaded on the uppeifendyof the rod 110. wA compression spring 124 surrounds the rod ;110 andbears at its upper end against the lower surface of ,jthehorizontally extending arm of the bell crank lever 112 and at its lower end against a roll 132 carried by the'post 70 is varied in accordance with the thickness of the work piece operated upon. 7

The machine as so far described has been in use for the lasting of stitchdown shoes for many years and 1s well-known in the trade as the stitchdownstaple lasting machine. In

lasting stitchdown shoes with the aidrof this machine the shoe upperis assembled upon a last with the marginal portion of thesole member to which the upper is to be secured extending beyond the last bottom. The marginal portion of the sole member is pressed upon the anvil block 7 Sand the treadle 98 is depressed raising the post 7 0 and the anvil block 78 in such amanner that .the shoe upper is wiped by thefforward surface of the nozzle 52 downwardly over the side of the last, the shoe upper being worked into the position indicated in Fig. 4 in which the shoe upper is indicated at 140, the sole member at .142 and'the last at 144. In operating this machine the treadle 98 is commonly engaged steps with his heel upon the treadle-22 thus (rendering the clutch operative and causing .the inclinedsurface130 of the wedge 10.4.to

'80'has been found; particularly helpfull'in is providednear its upper extremity with a by the-forepart of the operatoflsfooti Without removing the forepart of his foot from the treadle, which atthis time is substantially in engagement with the floor, the operator be forced beneath the roll 132, clampingtogether the outturned marginal portion'or flange of the shoe upper and the projecting portion of the sole member and driving 2 a staple through those parts so that itslegs are clenched against the surface of the anvil block 7 8 adjacent to the shoulder 80. The shoulder performing, this operation since it obviates the tendency of a sole member to slip on the inclined surface of-the anvil block 78 before the staple secures theparts together.

In the manufacture of stitchdown shoes, particularly childrensshoesof the smaller sizes, it is at times desired .to-perform the lasting operation without theu'se of staples. This is done either in the case of stitchdown shoes which have no liningsorthe linings of which areturned inwardly beneath an insole member noxlarger than the last bottom. Then, after the marginal portions of the flesh side of the shoe upper and of; the upper side of a sole member which projects beyond the margin of the last-have been coated with cement which has been allowed to become tacky,

'In order to make use of this capability of the machine, we have provided means which will now be described for rendering the staple-forming anddriving means of the machine inoperative without interfering with the movement of the work support or with the operation of the pressure applying means. For this purpose the lever 150,:which is fultheup'per is wiped over the side :of the last cru-med at 152 to thebracket40 and which carries feed roll 34, is extended upwardly and passage 154 through which passes a rod 156 pivoted at its forward end as shown at 158 to a depending latch member 160 pivoted at 162 to the head 10 of the machine (see Fig. 2'). At its lower end the latch member160 is arranged to engage beneath and to be-disenganged from a shoulder 1644formed on the lifting block 66 of the driver bar 56. The end of the rod .156 remote from the latch 160 is threaded to receive-a nut166and alock nut 168 which serve to limit the movement of a washer 170 surrounding the rod 156-and arranged for engagement with the lever 150 when that lever is swung in acounterclockwise direction as viewed in Fig. 2, thereby moving the latch member 160 to the left so that it will not interfere with the operation of the driver bar 56. A second washer 172 is mounted on the rod 156 to the right of the upper end of the lever 150, a spring 17 4 forming a yielding connection between the washer 172 and a shoulder formed on the rod 156 so that movement of the lever 150 in a clockwise direction, to the position of Fig. 2, yieldingly forces the latch member 160 to the right. Thus when the driver bar 56 is elevated, the lower end of the latch member 160 is caused to engage beneath the shoulder 164 of the lifting block 66, this being facilitated by suitably inclined or curved surfaces on the upper portion of the lifting block 156 and the lower portion of the latch member 160.

It will be observed that feed roll 34 is carried by the lever 150 below its fulcrum 152 so that when the lever 150 is swung in a clockwise direction to the position shown in Fig. 2. feed roll 34 will be removed from feed roll 32 so that the two rolls will not be onerative to feed wire to the severing and staple forming means. To facilitate this rocking movement of the lever 150. a handle 178 is secured thereto, the end of the handle beyond the lever 150 constituting a toggle member 1.80 pivoted to a second toggle member 182 which in turn is pivoted at 184 to the bracket 40. The arrangement is such that the movement of the lever 150 to the position shown in Fig. 2, in which the feed rolls are rendered inoperative and the driver is latched in elevated position, is effective to straighten the toggle 180, 182 and then to move the connection between the two toggle members slightly beyond the straight line connecting their fulcrums so that the toggle is effective to hold the lever 150 in the position shown. On the other hand, when the toggle is broken, the lever 150 is held with its upper end in engagement with the washer 170 and with the latch member 160 out of engagement with the lifting block 66 by a spring 190 hearing at one end against the lever 150 and at the other end against an upwardly extending portion of the bracket 40.

In the manufacture of cement lasted stitchdown shoes, the sole memberto which the upper is lasted is frequently the outsole of the shoe. There is danger of the lower surface of this sole member being marred by the shoulder 80 of the anvil block 78 and by the clenching surface of the anvil block. To prevent this. we have provided a sole protector 200 having a smooth work engaging surface and pivoted to the anvil carrier 76 it may be swung into the position shown in Fig. 4 when the machine is to be used for cement lasting and may be swung down as shown in Fig. 3 so that the anvil block 7 8 will be unobstructed when the machine is to be used for staple lasting. As illustrated herein, the sole protector has a portion 204 which, when in operative position, extends above the work engaging surface of the anvil block 7 8 and is provided on its under surface with a cavity 206 arranged to receive the shoulder 80 of the anvil block. This portion 204 extends from a substantially vertical portion 208 adjustably clamped as indicated at 210 to a grooved member 212 carried at the upper end of a plunger 214 passing through a sleeve 216, a lug 218 of which receives the pivotof the fulcrum 202. The formation of the engaging surfaces of the grooved member 212 and the vertically extending portion 208 of the sole protecting member are such as to permit arcuate adjustment of the sole protector 200 similar to the arcuate adjustment of the anvil block? 8 so that the sole protecting member can be swung into and out of position above the anvil block 78 whatever the adjustment of the latter may be. To permit the upper portion 204 of the sole protecting member 200 to swing past the shoulder 80 of the anvil block 78, the plunger 214 is connected to the sleeve 216 for a limited amount of endwise movement against the resistance of a spring 220 housed in the sleeve 216 and bearing at its upper end, as viewed in Fig. 4, against an internal shoulder formed in the sleeve 216 and at its lower end against a collar 222 secured to the rod 214. Thus engagement of the shoulder 80 in the cavity 206 acts impositively to hold the sole protecting member :200 in position over the anvil block 78 as shown in Fig. 4. It will be seen that when the sole protecting member 200 is swung down into the position shown in Fig. 3, thus exposing the anvil block 78, and when the lever 150 is swung in a counter-clockwise direction from the position shown in Fig. 2 so as to disengage the latch member 160 from the shoulder 164 of the lifting block 66 and to cause the feed roll 34 to move into operative relation to the feed roll 32, the machine is ready to be used for staple lasting stitchdown shoes in the manner in which that operation is commonly performed. When, however, the lever 150 is swung to the position of Fig. 2 so that the driver bar 56 is latched in elevated position and the feed roll 34 is carried to inoperative position, the sole protecting member 200 being swung upwardly from the position of Fig. 3 to that of Fig. 4, the machine is well adapted to be used for cement lasting. lVith the machine in this condition the shoe upper 140 is wiped into lasted relation to the last 144 and the sole member 142 as shown in Fig. 4, this being of the-work support caused? by the depression of treadle 98. Afterthis the 'power operated V causes them to adhere in lasted relation, A
